This study shows that multiresistant K. pneumoniae producing CTX-M-15 of MLST types 1, 11, 14, 17, 20, 35 and 36 are spreading as pathogens and colonizers among newborns and adult patients in Spain.

Key factors related to increased fosfomycin resistance in ESBL-EC causing UTIs could be the rapid growth in community use of fosfomycin, the widespread distribution of the 025b/B2 E. coli clone and the existence of a susceptible population comprising women residing in nursing home facilities.
